AF4-to-SAXS: expanded characterization of nanoparticles and proteins at the P12 BioSAXS beamline.
Article in Journal of synchrotron radiation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Biological small-angle X-ray scattering (SAXS) is a versatile and powerful technique for investigating the structural and biophysical properties of biologically and pharmaceutically relevant macromolecules and nanoparticles. SAXS offers detailed insights into macromolecular composition, size, shape and internal structure, while addressing key aspects such as oligomeric state, stability, molecular interactions, and conformational flexibility. Recently, asymmetrical-flow field-flow fractionation (AF4) was successfully coupled to SAXS, enabling online size-based fractionation and analysis of polydisperse samples. This approach allows precise, size-dependent characterization, offering significant advancements in the study of polydisperse systems. We have integrated an AF4 device at the P12 beamline at the European Molecular Biology Laboratory and implemented technical adaptations allowing full automation to make the system suitable for routine user access. We provide streamlined workflows and troubleshooting resources for both novice and advanced SAXS users thereby equipping them with clear guidance on performing AF4-SAXS measurements. The general principles of our set-up are easily adaptable to other beamlines which have integrated (or are planning to integrate) a similar system.
